I thought of that. Smallest gear motor I could find
cheaply was 1/2 HP!

I've seen three phase motors down to about 1/10 HP (small fan), but
those are really difficult to locate through any normal US sources.

I could strip out the PWM drivers from a brushless
fan motor and drive the windings via step down transformers,
conceivably. The test instruments revealed earlier still sound
like the best bet, (time and money wise) though.
